Chapter 4 Expansion products for content ingestion
4.3 IBM Content Collector
IBM Content Collector enables organizations to unlock the business value of content. Instead of merely archiving content, Content Collector breaks down silos of information by gathering and controlling it automatically. Corporations can transparently enforce compliance and operational policies while lowering the total cost of ownership. Business requirements are easily addressed with central administration, while classification and metadata makes the information more useful and reusable. Content Collector can start processes and workflows as documents are incorporated into the system. Content Collector collects, enhances, and manages content, making assets an active part in business processes.
Content Collector consists of four offerings:
Content Collector for Email

IBM Content Collector is licensed separately. There are other options that are far less expensive and may be better suited to your project. In particular, you might take a look at the Job Manager application from ECMG. It is a high volume content processing application that is designed for this type of work. It can be used for migrations of various types, including from Windows File System.

It's a separate product that you would need to get licensed to; not too expensive. In the old days of FileNet v3.5.2 the ingestion system was Records Crawler but starting v4 it has been replaced with IBM tool (ICC) which is even faster and has a bigger level of customization

Thanks for your quick response on my question,
As we already have FileNet P8 License and we are using that for some other project in my organization, I could go with the File Collector approach that suggested by Rodolfo.

The best solution is to use file net content manager V5.0 as it gives full content lifecycle and intensive document management which is capable for digital content like photos. It has many new characteristics and effectiveness which can help you manage unstructured enterprise content.
